Need a tune? Is this combo okay without?

[ozanracing]

The combo is: 306", Lunati custom 228*/232* @.050" W/ .501"/.513" Procomp 190cc heads, street heat intake, 30lbs injectors, fp@ 40-42psi, 70mm TB, 73mm
Vortech MAF with calibrated sample tube. longtubes. cr- ~9.2:1 16* timing.
Runs great, but I don't know if there are any lean points, think it'll be fine?
I'm going to be spraying a dry shot also, but for now I'm only concerned with NA.
I think it should be okay.

normally i would say to stay away from a dry shot but if you are going to be getting a custom tune than go for it. just make sure you use a window switch to keep it from spraying until the custom tune gives the engine enough fuel.

but as far as needing a tune i think you will be fine. that fuel pressure looks good enough to keep you from having any lean spots at all

Oh one more thing. I'm using a stock fuel pump...I have a new 190lph in the box in my shop just waiting for me to install it, but I was thinking: Know how injectors have a hp limit? like 19lbs are good up to 300rwhp or so? How about fuel pumps? At 6000rpm+ Is that stock pump being overworked and not providing adaquate fuel??

ps. I do have a digital msd window switch, I have it set to activate the n2o from 2600rpm to 5800rpm..thnks

good job on the window switch. id be careful until you put the new pump in. at the higher rpms it will definetly starve it for fuel

No new pump = kaboom

eesh...I never knew it was so bad...Guess I'll get over there and install it tomorrow after the dentist
Thanks for the heads up!
